DUMPlNG-SCOW.

SPECIFICATION forming. part of Letters Patent No. 238,607, dated March8, 1881.

Application filed August 12, 1880. (No model.)

To all whom it may concern:

Be it known that'I, FRANCIS-PIDGEON, of Saugerties, Ulster county, andState of New York, have invented a new and Improved Dumping-scow, ofwhich the following is a specification.

The object of my invention is to provide a new and improved dumping-scowwhich is simple in construction, can be dumped very easily when desired,and will float well.

The invention consists in a dumping-scow formed of two independentfloats which are connected by means of chains or ropes which pass fromthe bottom edge of the longitudinal side of one float to the bottom edgeof the corresponding opposite side of the other float, which chains orropes are attached to a windlass, whereby the floats can be united orseparated, as may be desired.

In the accompanying drawings, Figure 1 is a plan view of my improveddumping-scow. Fig. 2 is a cross-sectional elevation of the same on theline at a, Fig.1, and Fig. 3 is an end elevation of the same, showingthe manner in which the scow 1s dumped.

Similar letters of reference indicate corresponding parts.

The scow is formed of two floats or pontons, A B, of the same size,which are connected by ropes or chains 0 O, which are rigidly attachedto the deck of one of the floats--for instance, A-near one of thelongitudinal edges, and pass through hawser-tubes D D down to near thebottomedge of the said longitudinal side, pass over into the otherfloat, B, near to the bottom edge of its corresponding longitudinaledge, and then pass up through hawser-tubes E E to a Windlass, F,arranged on the deck of the float B. The hawser-tubes E of the float Bare preferably provided with a pulley, G G, at each end, as shown. Achain or rope, O, and Windlass F are to be arranged fore and aft of thescow.

If desired, the chain or ropes may be attached to the float A near thebottom, instead of on the deck.

The within-described scow is used as follows: The chains or ropes O arewound upon the windlasses F, so that the floats are united, as shown inFigs. 1 and 2. If desired, one ot the floats may be provided with alongitudinal flange or board at the upper longitudinal edge to cover thejoint of the two floats. The scow is then loaded and towed to itsdestination, where the chains or ropes are loosened. As the greatestweight rests on the adjoining inner edges or sides of the floats, thesewill be immersed deeper than the outer sidesthat is, the floats will beinclined toward each other-thereby causing the load to slide into thewater, whereby the floats are also separated, as shown in Fig. 3. Thefloats are then united and are ready for a new load. The dumping takesplace gradually, and not suddenly, and does not endanger the lives ofthe persons on the scow.-

Having thus described my invention, I claim as new and desire to secureby Letters Patcut- A dumping-scow consisting oftwo longitudinalfloat-sections, A B, having their adjacent sides connected near thelower part of each end by a chain working on a Windlass, as shown anddescribed.

FRANCIS PIDGEON.
